NONAQUEOUS ELECTROLYTE BATTERY

摘要

PROBLEM TO BE SOLVED: To reduce generation of defectives when manufacturing a nonaqueous electrolyte battery having a battery capacity not less than 100 Ah. SOLUTION: This nonaqueous electrolyte battery uses a separator 5 being composed of a polyethylene microporous film and polypropylene nonwoven fabric and having a thickness not less than 50 μm. Lithium cobaltate is used as a positive electrode active material, a graphitic carbon material is used as a negative electrode active material, and applying weight of a positive electrode active material mix is set to 4 g/100 cm2. A positive electrode plate 4 and a negative electrode plate 3 are laminated via the separator 5.
